Product Description

Product Description

 

The Hex Flange Head Self-Drilling Screw with EPDM Washer is a high-strength fastening solution specifically designed for metal-to-metal and metal-to-wood applications. Its large flange provides enhanced load distribution, while the EPDM bonded washer ensures a watertight seal, making it ideal for roofing, cladding, and steel structure projects.
 

_{1.Hex Head with Large Flange
Provides a secure grip and easy installation with power tools.
Distributes pressure over a larger surface area, reducing material damage.
2.Self-Drilling Tip
Allows direct penetration into metal without pre-drilling, improving work efficiency.
Designed for fast and precise drilling through steel, aluminum, and wood.
3.EPDM Bonded Washer
Ensures a waterproof and dustproof seal, preventing leaks in roofing applications.
Resistant to UV rays, extreme temperatures, and chemical corrosion.
4.Full or Partial Thread Options
Full Thread: Provides maximum grip strength and resistance to loosening.
Partial Thread: Allows for better clamping force in structural applications.}
 

Applications

^{1.Metal Roofing & Cladding: Securely fastens metal sheets and prevents water leakage.
2.Steel Structure Construction: Provides strong connections for industrial and commercial buildings.
3.Solar Panel Mounting: Ensures a firm hold for photovoltaic systems in outdoor environments.
4.General Outdoor & Industrial Use: Suitable for projects requiring weather-resistant fasteners.}
